The neutrophil-lymphocyte ratio (NLR) reflects inflammatory status. An elevated NLR has been reported to be a prognostic indicator in some malignant tumors. The aim of this study was to evaluate the clinical significance of the preoperative NLR in patients with primary gastric cancer. A total of 709 men and 319 women, with a mean age of 64.4 years, who(More)
BACKGROUND Although many reports have described laparoscopic pancreatic surgery, pancreaticoduodenectomy (PD) has not been widely accepted. The present study aimed to compare laparoscopy-assisted and open pylorus-preserving pancreaticoduodenectomy (PPPD) to investigate the feasibility, safety, and tumor clearance. METHODS Fifteen patients with(More)
A major challenge in laparoscopic liver resection to avoid massive hemorrhage from the transection plane. This study investigated 32 consecutive patients who underwent laparoscopic or laparoscopically assisted hepatic resection and had the hepatoduodenal ligament encircled by vessel tape using an Endo Retract Maxi as a tourniquet for complete interruption(More)
BACKGROUND Extended left hepatectomy including the middle hepatic vein (MHV) may potentially induce right paramedian sector congestion of the remnant liver. METHODS To prevent venous congestion in the right paramedian sector, we performed extended left hepatectomy including the left hemiliver and anterior segment, which drain into the MHV and left hepatic(More)
Although many reports have described laparoscopic minor liver resections, major hepatic resection, including right or left lobectomy, has not been widely developed because of technical difficulties. This article describes a new technique for performing laparoscopy-assisted right or left hepatic lobectomy using hilar Glissonean pedicle transection.(More)
Although many reports have described laparoscopic pancreatic surgery, laparoscopic pancreaticoduodenectomy (PD) has not been widely employed because of technical difficulties. This paper describes a totally laparoscopic pylorus-preserving PD performed for an intraductal papillary-mucinous neoplasm. After the laparoscopic resection, an end-to-side(More)
INTRODUCTION Although laparoscopic colorectal or gastric surgery has become widely accepted as a superior alternative to conventional open surgery, the surgical management of hepato-biliary-pancreatic disease has traditionally involved open surgery. Recently, many reports have described laparoscopic partial liver resection, lateral segmentectomy, and distal(More)
We report a case of pharyngeal metastasis of hepatocellular carcinoma (HCC). Any oral cavity involvement of HCC, especially pharyngeal metastasis, is extremely rare. The resected specimen contained a pedunculated polypoid lesion and histological examination revealed an epithelial tumor with a trabecular growth pattern, covered with intact squamous mucosa.(More)
A 56-year-old man was referred with lower rectal cancer showing anal canal invasion and liver metastasis. He underwent an abdominoperineal resection and a partial hepatectomy. Adjuvant therapy with tegafur-uracil and leucovorin was administered postoperatively. Lung metastasis was detected 2 years later and was resected. Right mandibular metastasis was(More)
Gallbladder involvement in patients with renal cell carcinoma (RCC) is extremely rare. We present a report of a 61-year-old man with a synchronous RCC metastasis to the gallbladder presenting as an intraluminal polypoid mass simulating primary gallbladder carcinoma. Enhanced abdominal computed tomography demonstrated a well-enhanced polypoid lesion in the(More)
